SYNOPSIS

DESCRIPTION

The wsreg_query_set_version() function sets the version specified by version in the query specified by query. If a version has already been set in the specified query, the resources associated with the previously set version are
released.

The wsreg_query_get_version() function gets the version string from the query specified by query. The resulting string is not a copy and must not be released by the caller.

RETURN VALUES

The wsreg_query_set_version() function returns a non-zero value if the version was set correctly; otherwise 0 is returned.

The wsreg_query_get_version() function returns the version from the specified query. If no version has been set, NULLt is returned. The resulting version string is not a copy and must not be released by the caller.

USAGE

The query identifies fields used to search for a specific component in the product install registry. By specifying the version, the component search is narrowed to all components in the product install registry that have the specified version.

Other fields can be specified in the same query to further narrow the search.
